Ulwakhiwo olunombhobho ongenamthungo

1 .Intshayelelo emfutshane yombhobho wolwakhiwo

Umbhobho ongenamthungo wesakhiwo (i-GB / T8162-2008) isetyenziselwa isakhiwo esiqhelekileyo kunye nesakhiwo somatshini wombhobho ongenamthungo.I-tube yensimbi engenamthungo yahlulwe kwiindidi ezahlukeneyo zokusetyenziswa.

Umbhobho wensimbi engenamthungo wesakhiwo (i-GB/T14975-2002) ngumbhobho oshushu oqengqelekayo (owongeziweyo, owandisiweyo) kunye nombhobho otsalwa ngokubanda (oqengqiwe) owenziwe ngentsimbi engatyiwayo esetyenziswa kwikhemikhali, kwipetroleum, kwilaphu, ezonyango, ekutyeni, koomatshini kunye nakwimichiza. amanye amashishini, imibhobho ekwaziyo ukumelana nomhlwa kunye namalungu olwakhiwo kunye namalungu.

I-GB/T8162-2008 (umbhobho ongenamthungo wesakhiwo) isetyenziselwa ubukhulu becala kunye nesakhiwo soomatshini. Izinto ezimele ummeli (brand) : carbon steel 20, 45 steel, Q235, i-alloy steel Q345, 20Cr, 40Cr, 20CrMo, 30-35CrMo , 42CrMo njalo njalo.

Umbhobho wentsimbi ongenamthungo

Ngenxa yenkqubo yokuvelisa yayo yahlukile, yahlulwe yaba ityhubhu yentsimbi eshushu eqengqelekayo (extruded) ingenamthungo kunye nebandayo etsalwa (iqengqiwe) ingenamthungo yentsimbi ityhubhu ezimbini iindidi.Umbhobho obandayo (oqengqiwe) wahlulwe waba ngumbhobho ojikelezayo kunye nombhobho omilise okwesibini. iintlobo.

A.Amagqabantshintshi okuqukuqela kwenkqubo

Ukuqengqeleka okushushu (ityhubhu yentsimbi ekhutshiweyo engenamthungo) : ityhubhu engqukuva → ukufudumeza → ukugqobhoza → ukuqengqeleka okuqengqelekayo okuthathu, ukuqengqeleka okuqhubekayo okanye ukukhupha → ukuhluba ityhubhu → ukusika (okanye ukunciphisa) → ukupholisa → ityhubhu engenanto → ukolula → uvavanyo loxinzelelo lwamanzi (okanye isiphene ubhaqo) → ukuphawula → ugcino.

Umzobo obandayo (ukuqengqeleka) ityhubhu yentsimbi engenamthungo: ityhubhu engqukuva → ukufudumeza → ukugqobhoza → isihloko → ukuqhola → ukuchola → ukuthambisa (iplate yobhedu) → umzobo obandayo ohamba ngeendlela ezininzi (ukuqengqeleka okubandayo) → ityhubhu engenanto → unyango lobushushu → ukulungisa → uvavanyo loxinzelelo lwamanzi (ukubona iziphene) → ukuphawula → ugcino.

Umbhobho wentsimbi ongenamthungo wenqanawa: GB5312-1999 12.13, zonke iintlobo ze-alloy tube 16Mn, 27SiMn, 15CrMo, 35CrMo, 12CrG0, 4 12Cr1MoV,15CrMo

Ukongeza, kukho i-GB/T17396-2009 (ityhubhu yentsimbi engenamthungo eshushu eqengqelekayo yepropu yehydraulic), i-GB3093-1986 (ityhubhu yentsimbi engenamthungo ephezulu yoxinzelelo lwenjini yedizili), GB/T3639-1983 (itsalwa ngokubanda okanye ebandayo- ityhubhu yentsimbi echanekileyo iqengqiwe, i-GB/T3094-1986 (intsimbi engenamthungo etsalwa ngokubanda iityhubhu, iityhubhu zetsimbi ezikhethekileyo, i-GB/T8713-1988 (iityhubhu zentsimbi ezingenamthungo ezine-diameter echanekileyo yangaphakathi ye-hydraulic kunye ne-pneumatic cylinders), i-GB13296-1991 (iityhubhu zentsimbi ezingenamthungo kwiibhoyila kunye nokutshintsha ubushushu), GB/T14975-1994 ( iityhubhu zentsimbi ezingenamthungo ezisetyenziselwa ulwakhiwo), I-GB/T14976-1994 (Iityhubhu zentsimbi ezingenamthungo nezinedayamitha echanekileyo yangaphakathi yehydraulic kunye ne-pneumatic cylinders)Iityhubhu zentsimbi ezingenamthungo zokuthutha ulwelo GB/T5035-1993 (iityhubhu zentsimbi ezingenamthungo ze-axle bushing yemoto), i-API SPEC5CT-1999 kunye netyhubhu), njl.

I-2, umgangatho waseMelika: i-ASTM A53 - ASME SA53 - I-Boiler kunye ne-Pressure Vessel ikhowudi inqanaba eliphambili lokuvelisa okanye iklasi yentsimbi: A53A, A53B, SA53A, SA53B

Ifomula yobunzima betyhubhu engenamthungo: [(idayamitha yangaphandle - ubukhulu bodonga)* ubukhulu bodonga]*0.02466=kg/m (ubunzima ngemitha nganye)
